Line
Segment Tap where you want one endpoint to be and press E .
Tap where you want the other endpoint to be and press
E . A segment is drawn between the two end points.
Keyboard shortcut: r
Ray Tap where you want the endpoint to be and press E .
Tap a point that you want the ray to pass through and press
E . A ray is drawn from the first point and through the
second point.
Line Tap at a point you want the line to pass through and press
E . Tap at another point you want the line to pass
through and press E . A line is drawn through the two
points.
Keyboard shortcut:
j
Vector Tap where you want one endpoint to be and press E .
Tap where you want the other endpoint to be and press
E . A vector is drawn between the two end points.
Angle bisector Tap the point that is the vertex of the angle to be bisected (A)
and press
E . Tap another point (B) and press E .
Tap a third point (C) and press E . A line is drawn
through A bisecting the angle formed by AB and AC.
Perpendicular
bisector
Tap one point and press E . Tap another point and
press E . These two points define a segment. A line is
drawn perpendicular to the segment through its midpoint. It
does not matter if the segment is actually defined in the
Symbolic view or not. Alternately, tap to select a segment and
press
E .
If you are drawing a perpendicular bisector to a segment,
choose the segment first and then select Perp. Bisector from
the Line menu. The bisector is drawn immediately without you
having to select any points. Just press
E to save the
bisector.
